低渗透油藏的试井资料中，早期资料占有较大的比例，目前对这类资料尚无成熟的解释方法。通过对早期资料特征的研究，认为对早期资料校正的关键是对续流效应的校正，据此提出了新的早期资料解释方法及相应的表皮系数计算公式。该方法能同时对续流和表皮效应进行校正，从而达到正确解释早期资料的目的，它具有如下特点：①可解释低渗透油藏由于测试时间不够未出现径向流的试井资料；②用于低渗透油藏待测试井的试井设计，可缩短测试时间；③提高试井资料解释率和解释结果的精度；④可较大幅度地缩短关井测试时间，从而降低试井成本，减少关井的产量损失，提高低渗透油藏的试井工作效率。应用表明，该方法实用性、通用性较强，较好地解决了早期资料的解释难题。图３表１参７（陈志宏摘） Well testing data of low permeability reservoirs occupy a large proportion of early data, so there is no mature explanation for such data. Through the research on the characteristics of early data, it is considered that the key to correcting the early data is to correct the free-wheeling effect, and a new method of early data interpretation and the corresponding formula of skin factor are proposed. The method can correct freewheeling and skin effect at the same time so as to achieve the purpose of correctly interpreting the early data. It has the following characteristics: ① Well test data that can explain radial flow in low permeability reservoir due to insufficient test time; Well test design in low permeability reservoirs to be tested can shorten the test time; (3) improve the interpretation rate of well test data and the accuracy of interpretation results; (4) can greatly shorten the test time of well shut down, thus reducing well testing costs and reducing Shut down the production loss, improve the efficiency of well testing of low permeability reservoirs. The application shows that the method is practical and versatile, and solves the difficult problem of early data interpretation. Figure 3 Table 1 Reference 7 (Chen Zhihong)
