Embodiment 1

[0076] The monitoring method of the gravel filling process adopts the above-mentioned monitoring system and the real-time monitoring method. After the monitoring site of the sand control well is arranged, the monitoring of the whole process of gravel filling is started. The specific steps are as follows:

[0077] Step 1: Arrange the monitoring site

[0078] Before the sand control equipment and sand control materials enter the sand control well site, according to the actual environment around the sand control well 8, a group of ground magnetometers 10 are arranged on the ground 13 with the sand control well 8 as the center, and the ground magnetometers 10 are collected through the ground magnetometer and data collection. Link to the processing center communication line 23 with the data acquisition and processing center 7;

[0079] Preferably, a group of sand control well magnetometers 11 is also arranged near the sand control section of the sand control well 8, and the sand co...

Embodiment 2

[0092] The working method of repeatedly monitoring the gravel packing state after the sand control well is put into production for a period of time adopts the above-mentioned monitoring system, including the following steps:

[0093] Step 1: Arrange the monitoring site

[0094] After the sand control well has been put into production for a period of time, the gravel filling state operation is repeatedly monitored. According to the actual environment around the sand control well 8, a group of ground magnetometers 10 are arranged on the ground 13 with the sand control well 8 as the center, and the ground magnetometers 10 are passed through the ground magnetometer. Data collection and processing center communication line 23 is connected with processing center 7;

[0095] Preferably, a group of sand control well magnetometers 11 is also arranged near the sand control section of the sand control well 8, and the sand control well magnetometers 11 are connected to the data collection...

Embodiment 3

[0101] The working method of the multi-layer gravel packing real-time monitoring method adopts the above-mentioned monitoring system, including the following steps:

[0102] Step 1: Arrange the monitoring site

[0103] Before the sand control equipment and sand control materials enter the sand control well site, according to the actual environment around the sand control well 8, a group of ground magnetometers 10 are arranged on the ground 13 with the sand control well 8 as the center, and the ground magnetometers 10 are collected through the ground magnetometer and data collection. The communication line 23 of the processing center is connected with the processing center 7;

[0104] Preferably, a group of sand control well magnetometers 11 is also arranged near the sand control section of the sand control well 8, and the sand control well magnetometers 11 are connected to the data collection and processing center 7 through the communication line 24 of the data collection and ...

Abstract

The invention relates to a gravel pack filling monitoring system and method. The gravel pack filling monitoring system comprises a magnetic particle container, a gravel pack container, a gravel pack mixer, a sand-carrying fluid container, a sand mixing truck, a high-pressure pumping set, a data acquisition and processing center, a ground magnetometer, a magnetic particle conveying pipeline, a gravel pack conveying pipeline, a evenly-mixing gravel pack conveying pipeline, a sand-carrying fluid conveying pipeline, a first sand-mixing fluid conveying pipeline, a second sand-mixing fluid conveying pipeline and a ground magnetometer and data acquisition and processing center communication pipeline, wherein the ground magnetometer monitors magnetic parameter changing from the ground, the data acquisition and processing center is connected with the data acquisition and processing center communication pipeline through the ground magnetometer, and the data acquisition and processing center collects and stores the measured information of the ground magnetometer and calculates and displays the gravel pack distribution state. The gravel pack filling monitoring system can track the transporting and distributing state of gravel pack in a sand-prevention well section from the ground, the well and/or an adjacent well during gravel pack filling and can achieve repeated detection on gravel pack distribution after production of the sand-prevention well.

Description

technical field [0001] The invention belongs to the field of petroleum exploration and development, and in particular relates to a monitoring system and method for gravel filling, in particular to a magnetic medium-based gravel filling monitoring system and monitoring method. Background technique [0002] During the production of oil and gas wells, due to the influence of geological, engineering, production and other factors, sand production is inevitable. When a large amount or continuous sand production is serious, it will block the tubing, damage downhole and surface equipment, shorten the life of the oil well, and reduce the productivity of the oil and gas well. etc., which pose serious challenges to the efficient development of oil and gas fields. [0003] In order to ensure the normal production of oil and gas wells and increase production, sand control and sand control have become common demands in the production process of oil and gas wells. The current sand control...
