Second, the data checking and correction process, to understand the various sources of measurement error, its three main areas: equipment error (determined by the instrument itself, is an objective source of error), observation error (due to the technical level personnel a result of belonging to a subjective source of error), external influence error (subject, such as temperature, atmospheric refraction effects of external factors such as these factors are also constantly changing and difficult to control, belonging to a variable source of error).

其次，在对数据的检查和矫正的过程中，明白了各种测量误差的来源，其主要有三个方面：仪器误差（仪器本身所决定，属客观误差来源）、观测误差（由于人员的技术水平而造成，属于主观误差来源）、外界影响误差（受到如温度、大气折射等外界因素的影响而这些因素又时时处于变动中而难以控制，属于可变动误差来源）。

Theoretical calculation shows the anomaly of reservoir tidal gravity is measured at μGal level, while the measured data shows the observation error of such tidal gravity at 10-μGal level. This indicates that the data noise may well disguise real anomalies, and therefore that the lack of measured anomaly data does not necessarily equate to the lack of oil and gas reservoir underneath. The actual observed tidal gravity anomaly can reach tens of μGal. Though it is more than three times the observation error, we can not attribute it to the reservoir-induced tidal gravity anomaly.

理论计算表明，油藏潮汐重力异常在微伽量级，而实际资料表明潮汐重力的观测误差为10 μGal量级，油藏潮汐重力异常可能会被噪声淹没，所以没有观测到潮汐重力异常不等于地下没有油气；实际观测的潮汐重力异常可达数十μGal，即使超过观测误差的3倍，也不能将它直接归因于油藏产生的潮汐重力异常。
