【摘要】：受低孔、低渗、低丰度等基本地质特征的影响,苏里格气田面临单井产量低、压力下降快等开发难题。为提高单井产量和气藏采收率,实现区块优质、高效开发,以地质工程一体化理念为指导,在苏10、苏11、苏53区块开展一系列技术研究和现场试验。工程地质一体化主要体现在以下几个方面:1确定区块开发方式。苏10区块以直井、丛式井开发为主,井间产能接替;苏11、苏53区块分别以丛式井和水平井开发为主,区域产能接替。2优化方案设计。通过地质工程结合,优化水平井方位、水平段位置、储层改造方式等参数,实现储层最大动用。3实现水平井工厂化作业。在苏53区块优选13口井(10口水平井)开展水平井工厂化作业,探索出了一套以"方案设计最优化、工程技术模板化、施工作业流程化、作业规程标准化、资源利用综合化、队伍管理一体化"为核心的工厂化作业模式。4侧钻水平井技术取得重大突破。2015年实施的2口侧钻水平井,平均砂岩钻遇率均超过90%,平均单井控制储量0.96×108m3,初期日产量接近6.0×104m3,实现了地质到工程的整体突破。5地面流程合理化。按着地面服从地下的思路,水平井整体开发达到了简化集输流程、便于管理、节省投资的效果。
[Abstract]:Affected by the basic geological characteristics such as low porosity, low permeability and low abundance, Sulige gas field is faced with the development problems such as low single well production and rapid pressure drop. In order to improve single well production and gas reservoir recovery, the block can be developed with high quality and high efficiency. Guided by the concept of geological engineering integration, a series of technical studies and field tests were carried out in blocks Su 10, Su 11 and Su 53. The integration of engineering geology was mainly reflected in the following aspects: 1 determining the development mode of block. Cluster well development is the main development and cross-well productivity replacement; block Su 11 and Su 53 are mainly developed by cluster wells and horizontal wells, respectively, and regional productivity replacement is optimized by design of .2 optimization schemes. Through the combination of geological engineering, the azimuth and horizontal section position of horizontal wells are optimized. Reservoir modification mode and other parameters, to realize the maximum reservoir production of .3 to realize the factory operation of horizontal wells. In Su53 Block, 13 wells and 10 horizontal wells are selected for industrial operation. A set of "optimal scheme design" has been explored. Formalization of engineering technology, construction operation flow, standardization of operation rules, integration of resource utilization, The technology of sidetracking horizontal wells with the core of "team management integration" has made a great breakthrough. In 2015, 2 sidetracking horizontal wells were implemented. The average rate of sandstone drilling is more than 90, the average controlled reserves of single well is 0.96 脳 108m3, the initial daily production is close to 6.0 脳 104m3, the overall breakthrough of surface flow from geology to engineering has been realized. The whole development of horizontal well can simplify gathering and transportation flow, be easy to manage and save investment.
