车66块砂砾岩体储层地质特征及试油效果评价

Geological Characteristics and Effect Evaluation of Well Test in Glutenite Reservoir in Block Che66

车66块位于车镇凹陷北部陡坡带西段,其主力油层为沙三下砂砾岩体,油层具有油气藏埋藏深,岩性复杂,储层物性差的特点。在总结分析该区块的地层特征、储层物性以及试油试采特征的基础上,评价该块储层改造工艺和试油效果,对指导该区下步勘探开发具有积极的意义。

Block Che66 locates at the western part of northern actic region of Chezhen sag, the main oil reservoirs are lower Glutenite in Sha-3 section, and the reservoirs are deep buried with complex lithologies and poor physical properties. Based on analysis of its geological features, reservoir properties, results of well test and production test of block Che66, stimulation treatment technique and well test effect are evaluated, and the evaluation is significant to the next stage of exploration and development of the block.
