摘要:
鄂尔多斯盆地DN气田为典型的低孔低渗致密砂岩储层，采用常规地层压力测试，干点过多，测试成功率仅为3303%。小直径地层压力测试器测试时，定点深度以自然伽玛为基准，仪器下放和数据传输均由电缆完成，一次下井能进行多点测量，预测室大小可根据储层特征在0～20 ml之间调节。在DN气田致密砂岩储层应用，测试总成功率达590%。依据小直径地层压力测试器测试数据，结合地层测试、试气情况，区域特征，以及4口典型井资料进行分析，其结果为区块储层动用情况、纵横向连通性判断，以及新井投产方案选择等提供了可靠依据。小直径地层压力测试器的成功应用，为致密砂岩油气田快速、高效获得地层压力提供了新的测试评价方法。
Abstract:
DN gas field in Ordos basin is a typical tight sandstone reservoir with low porosity and low permeability. When conventional formation pressure test is used, there are too many dry points, and the success rate of test is only 3303%. When the small diameter formation pressure tester is used for testing, the fixed point depth is based on the natural gamma ray, the running of instrument and data transmission are completed by the cable, the multipoint measurement can be carried out by one trip test operation, and the size of the prediction chamber can be adjustedbetween 0~20 ml according to the reservoir characteristics. This method has been applied in tight sandstone reservoir of DN gas field, and the total success rate of test is 590%. According to the test data of small diameter formation pressure tester, combined with formation test, gas test situation, regional characteristics, and data of four typical wells, the results provide reliable basis for the block reservoir production situation, judgment of vertical and horizontal connectivity, and selection of new well production scheme. The successful application of smalldiameter formation pressure tester provides a new test and evaluation method for fast and efficient formation pressure acquisition in tight sandstone oil and gas fields.
