横向差异速度比值（LateralDifferentialVelocityRatio，简称LDVR）分析方法是一套用常规速度资料辅助进行；电气检测的方法。本方法基于差异层间速度分析（DIVA）方法和砂泥岩指数计算公式并作相应的改进。运用LDVR方法对塔里木盆地的HLHT（包括DHT油田）、TD、TZ、BC、YKL以及LN等地区6个区块的4个层系进行计算，初步取得了良好效果，特别是对LN以及BC的部分区块的钻前预测结果，均与实际钻井情况相符。 The Lateral Differential Velocity Ratio (LDVR) analysis method is a set of methods that are assisted by conventional velocity data; the electrical test. The method is based on the DIVA method and the calculation formula for sand-shale index and makes corresponding improvements. Using LDVR method to calculate the four strata of six blocks in HLHT (including DHT oilfield), TD, TZ, BC, YKL and LN in the Tarim Basin, and achieved good results initially, especially for LN and BC The prediction results of some blocks before drilling are all consistent with the actual drilling conditions.
