The average daily production of more than 80 cubic meters, known as "Blue Gold" of natural gas has been the pride of Xinglongtai oil production plant of Liaohe Oilfield, it is not only a new growth point of economic benefits for the factory, Liaohe Oilfield contributed 70% of the supply of gas products.

在以稠油为主的辽河油田，兴隆台采油厂具有丰富的天然气资源和开发优势。近年来，这个厂通过大力提升天然气经济产量的贡献率，为辽河油田增添效益砝码。去年，该厂累计完成外供天然气量2.58亿立方米，超产1730万立方米。

In the Liaohe Oilfield, Xinglongtai oil production plant has abundant natural gas resources and development advantages. In recent years, this plant by vigorously promoting the contribution rate of natural gas production, to increase the effectiveness of the Liaohe Oilfield weight. Last year, the plant accumulated for natural gas 258 million cubic meters, 17 million 300 thousand cubic meters of production.

有优势亦有阻碍

There are advantages and obstacles

3月21日，兴隆台采油厂榆树台油田停产气井台34-28井采取补层合采措施后，保持日产1.1万立方米的自喷工业气流，措施后平稳生产26天，累计增气25.7万立方米。同一天，采油作业一区于六站站长李岩打开长停井套管气回收阀门，确保天然气“颗粒归仓”。前者是措施增气，后者是管理节气，两项措施相得益彰。

In March 21st, Xinglongtai oil production plant oil production wells yushutai Taiwan 34-28 wells take up layer commingled production measures, maintain Nissan 11 thousand cubic meters of industrial gas flowing, measures of stable production for 26 days, the cumulative increase of 257 thousand cubic meters of gas. On the same day, oil production operations in the six District of the station Li Yan opened a long stop casing gas recovery valve to ensure that the natural gas particles into the warehouse". The former is a measure to increase gas, which is the management of solar terms, the two measures complement each other.

“兴采厂以生产稀油为主，油井不产天然气是不可想象的，仅这项优势你们采油厂就能获得更好的效益产出。”一位石油技术专家在授课时对该厂天然气开发优势这样评价道。

"Xing mining plant in the production of thin oil based, oil wells are not natural gas can not be imagined, only the advantage of your oil production plant will be able to get a better output." An oil technology expert in the teaching of the advantages of the development of the natural gas plant evaluation.

兴采厂稀油井生产通常带有伴生气，尽管这些油井溶解气产量高低不定，但开采成本远低于稠油井生产。据了解，目前该厂气层气、溶解气可采储量采出程度高达90%和88%，但2015年无新增天然气储量，剩余气层在各油田平面分布零散，难以实施整体新井部署，并且主力气层连同系数高达60%，连续多年超负荷措施挖潜，各油气田对天然气的大规模高速开发已经到了衰竭阶段，层间接替潜力越来越小。

Singtex dilute oil production factory usually with gas, although the oil dissolved gas yield is not fixed, but far less than the cost of mining heavy oil production. It is understood that the current plant gas, dissolved gas can be taken out of a high degree of up to 90% and 88% of recoverable reserves, but in 2015 no new natural gas reserves, residual gas in the oil distribution is scattered, difficult to implement the overall deployment of Nii, and together with the main gas coefficient as high as 60%, for many years the overload measures to tap the potential of each oil and gas to gas mass rapid development has reached a stage of failure, more and more small interlayer replacement potential.

控递减也要重增量

Control the decline should be increased

由于油品品质好、开发成本较低，兴古潜山一度被誉为“兴采聚宝盆”，然而这块“宝地”的产气量近年来快速下降，兴古潜山由高峰时的日产气66万立方米降低至目前的36万立方米。

Because of good quality oil, lower development costs, and ancient Qianshan, once known as "singtex cornucopia", but this "treasure house" of the gas production in recent years the rapid decline, from a peak of Xing ancient Qianshan Nissan 660 thousand cubic meters of gas is reduced to the current 360 thousand cubic meters.

为实现潜山油藏增能保压，该厂制定注气方案，开展前期非烃类气驱实验，有效减缓了潜山油藏递减的速度。去年，兴气19井和兴283井调层后均获得日产气超过2万立方米的高产气流，成为兴采地质措施“开源”的经典案例。2017年，该厂加快了兴古潜山天然气气驱前期准备工作，预计10月份进入现场实施，标志着潜山增能补压技术进入新阶段。

In order to realize the energy conservation and pressure maintaining of Qianshan reservoir, the gas injection scheme was developed and the non hydrocarbon gas flooding experiment was carried out in the early stage, which effectively slowed down the rate of decline of Qianshan reservoir. Last year, Xing Qi 19 wells and Xing well after the transfer of the layers were obtained more than 20 thousand cubic meters of gas production of high gas flow, Xing Xing geological measures to open source, the classic case of "". 2017, the plant to speed up the ancient Qianshan gas and gas drive preparatory work, is expected to enter the site in October, marking the Qianshan increase energy pressure technology into a new stage.

同时，该厂努力在老区上做天然气的“加法”。兴采厂地质技术人员一方面通过对构造、油气水分布的重新认识，细化单砂体多层次对比，寻找微构造高点，强化“四性”关系分析，筛选优化高效气井措施。另一方面，通过加强井震结合落实潜力区域的微构造高点，部署高气油比井侧钻减缓天然气产量递减趋势。

At the same time, the factory efforts to do in the old area of natural gas addition". Singtex factory technical personnel on the one hand, the geological structure, oil and gas and water distribution of the new understanding, refinement of the single sand body multi-level comparison, find the top of micro structure analysis, strengthening the "four" relationship, optimization and screening of efficient wells measures. On the other hand, by strengthening the combination of well seismic and micro structure of the potential area, the deployment of high gas to oil ratio drilling to slow down the decline trend of natural gas production.

荣兴屯油田是开发多年的老区块，实施侧钻成为近几年挖潜天然气的主要手段。荣201-19C井措施前低压低产，在测井指标进行对比分析、综合研究后，拟定待射孔层位经过调层后开井，使用3毫米油嘴自喷生产，日产气1.2万立方米。

Rongxingtun oilfield is the old block development for many years, the implementation of lateral drilling in recent years has become the main means of tapping the potential of natural gas. Rong 201-19C wells in low pressure and low production measures, logging index comparative analysis and comprehensive research, to be adjusted after the perforation layer layer wells, using a 3 mm nozzle flowing production, Nissan 12 thousand cubic meters of gas.

截至目前，该厂高气油比油井部署投产11口，初期日增气7万立方米；高气油比措施22口，初期日增气24万立方米；共实施侧钻井16口，日增气1.5万立方米，阶段累计增产天然气185万立方米。

As of now, the plant of high gas oil ratio well deployment of production 11, the initial increase of 70 thousand cubic meters of gas; high gas oil ratio measures 22, the initial increase of 240 thousand cubic meters of gas; the implementation of lateral drilling 16, daily 15 thousand cubic meters of gas, the cumulative increase of 1 million 850 thousand cubic meters of natural gas phase.

讲策略也讲方法

Speaking strategies and methods

“热炉耗气量占全厂天然气消耗的三分之二，针对春季转暖的实际，去年从4月份开始，在不到一个月的时间里，共实施油井停炉冷输180台，累计节气580万立方米。对153台炉子实施控温输油，每天可节气700立方米。”兴采厂生产运行处一位负责人介绍说。

The "hot stove gas consumption of the total natural gas consumption of 2/3, according to the actual spring warming, from the beginning of April last year, in less than a month's time, the implementation of the wells stop furnace cold transport 180, a total of 5 million 800 thousand cubic meters of solar term. 153 furnace temperature control oil, solar energy can be 700 cubic meters per day." Xing mining plant production and operation of a person in charge said.

节约从日常工作中的点滴小事做起，在“细枝末节”中挖掘效益。该厂基层单位通过采取控制水套炉温度、安装节能炉、加热炉维护等多项节气挖潜措施，日节约自耗气约2.9万立方米；每月各中心站利用高压水龙管带，收集长停井天然气在3万立方米以上；80%以上采油自然站安装采暖阀，值班室温度不超过18摄氏度，循环泵房、配电间等房间控制在10摄氏度以下……

Savings from the daily work of the little things to start, in the minutiae of mining benefits. The factory units by taking control of water jacket furnace temperature, the installation of energy-saving furnace, heating furnace maintenance and other measures on saving solar term, the gas consumption of about 29 thousand cubic meters; by using the high pressure hose with monthly center station, collect long stop wells natural gas 30 thousand cubic meters; more than 80% natural oil production station installed heating valve, on duty room temperature not exceeding 18 degrees Celsius, circulation pump room, power distribution room and other rooms at 10 degrees celsius......

在抓好油井生产挖潜的同时，这个厂积极寻找日常管理中的节气新路径，通过改造和设计在增气创效过程中发挥了四两拨千斤的作用。

At the same time do a good job in tapping the potential of oil production, the factory actively looking for a new path in the daily management of the solar cycle, through the transformation and design in the process of increasing gas efficiency played a role in the 42 dial.

该厂采油作业一区优化油井控制套压方法，既不影响原油进系统生产，又能兼顾控套整体效果，目前该种方法适用于全厂56口单井，平均每口单井日均可回收天然气2.5万立方米；采油作业五区在推行“自耗气系统回收套管气流程”以来，在作业区内19口油井采取该方法，实现日均回收套管气4500立方米，年累计收套管气85万立方米。

The factory production operation area to optimize well casing pressure control method, which does not affect the production of crude oil into the system, but also consider the overall effect of the control set, the method is applicable to all the 56 wells, the average single well day can be recycled 25 thousand cubic meters of natural gas; oil production areas in the implementation of the "gas consumption system the recovery process of casing gas" has been in operation in the region 19 wells adopt this method, realize the daily recovery of casing gas 4500 cubic meters, annual accumulated close to 850 thousand cubic meters of gas pipe.
